Verticalrollermills (VRM) are an energyefficient alternative to conventional grinding technology. One reason is the dry inbed grinding principle. Results of extensive test works with two types of magnetite iron ores in a Loesche VRM are presented here. Within these test works, mill parameters like grinding pressure, separator speed and dam ...

The cost of the raw material per one piece is given by this formula: In the previous example, assuming 0,7 Euro per kg as the Material cost per kg, and density of steel 7,8 kg/dm3 we obtain: RAW MATERIAL COST = 7 * 5 * 0,01 * 7,8 * 0,7 = 1,91 Euro. This procedure has to be repeated with each of the raw materials entering the process.

Therefore, a roller mill may be a better alternative to a hammermill for swine feed processing [1]. However, roller mills require more vigilance to maintain a gap width that will produce the targeted particle size. Roll gap width will change as rolls wear and grain qualities change. Hammermills will require less monitoring by comparison.
